Spatial distance between sites of sampling associated with genetic variation among Neospora caninum in aborted bovine foetuses from northern Italy

Table 4 Linear regression models to characterize the association between genetic distance (Bruvos’s genetic distance) of N. caninum isolates and the spatial distance of the sampling sites or the time between dates of sampling
